Customising Creat User Wizard

Hello

This code was translated from c# but I keep getting this error.

 The variable name '@UserId' has already been declared. Variable names must be unique within a query batch or stored procedure

Any ideas I have tried changing the user id name but no luck. thanks

 

 Partial Class userInherits System.Web.UI.Page

 Protected Sub CreateUserWizard1_CreatedUser(ByVal sender As Object, ByVal e As System.EventArgs) Handles CreateUserWizard1.CreatedUser

Dim UserNameTextBox As TextBox

UserNameTextBox = CreateUserWizardStep2.ContentTemplateContainer.FindControl("UserName")Dim DataSource As SqlDataSource = CreateUserWizardStep2.ContentTemplateContainer.FindControl("InsertExtraInfo")

Dim user As MembershipUser = Membership.GetUser(UserNameTextBox.Text)Dim UserGUID As Object = user.ProviderUserKeyDataSource.InsertParameters.Add("UserId", UserGUID.ToString())

DataSource.Insert()

End Sub

End Class
